Abstract:
Musculoskeletal deficits remain significant impediments to the function and independence of children and adolescents following successful treatment of Central Nervous System Tumors (CNS) tumors. The sequelae often impair the function of the upper and lower extremities and manifest themselves as difficulties in gross and fine motor skills, which encompasses self care and walking. Overall, the five-year survival rate for children younger than 15 years with brain tumors is between 60 to 90 percent. Approximately two-thirds of survivors have long term neurological deficits. These neurologic deficits often manifest themselves as musculoskeletal abnormalities. It is essential to recognize the potential consequences of a CNS tumor and its associated treatments in an effort to prevent disability. Following the initial neurosurgical and oncologic treatment, the acute and chronic stages of the orthopaedic care for these patients differ significantly. Many of the rehabilitation and treatment principles for brain tumor patients have evolved from the principles used in stroke and traumatic brain injury. Orthopaedic treatment specifically includes preventing, identifying, and treating spasticity, contractures, bony and spinal deformities, and gait abnormalities.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
